+The processor also support Direct Memory Access(DMA). This automates the buffering of transmitted bytes, which relieves the processor of executing code to fetch each byte and store it in a buffer. This can be done both while transmitting and receiving data.

 	The data received \texttt{8bits} at a time. Each data point transmitted contains \texttt{32bits}, formatted as a standard \texttt{IEEE 754 float}. The data is shifted into a temporary \texttt{32bit unsigned int} and then a \texttt{memcpy()} is executed from the \texttt{int} to a \texttt{float}. The data points are then sent over to \texttt{MSP} and stored. 
 	
+	Due to the high transmission rate of the MTi, DMA buffering has been implemented to relieve
+	the processor of constant code execution of receiving each byte. However transmission to the MTi is interrupt driven, due to the small amount of data that has to be sent. Something which is only executed upon launch, to configure the MTi.
